To shape a feather, gently bend the quill, working with small sections at a time, until you have curved the entire length of the feather. Wider and stiffer quills are shaped best using a rounded object like a pen or marker. Peacock swords and goose biots are shaped best with a thinner edge (like closed scissors), using the same technique you might use to curl ribbon for a gift. More dramatic shaping can be achieved with a curling iron set on very low heat.
